Posted: Updated:

Story Highlights

What you need to know

The STORMTracker Weather Team is tracking a major pattern change that will bring wintry weather to the Treasure State.

Significantly colder air is expected to move into Montana later this week, along with widespread snow.

Anyone traveling after Wednesday should be prepared for winter driving conditions that could result in travel slow-downs.

It's still a bit too early to determine exactly how much snow is going to fall and where, but confidence is growing that this week's weather will have considerable impacts on travel.

First look: snow forecast

Keep in mind that this storm is still a few days out and this snow forecast will change.

STORMTracker meteorologist Mike Rawlins says the heaviest snow will likely fall in the Rocky Mountains and adjacent plains of north-central Montana. Lesser snow amounts are expected over southern Montana due to warmer temperatures resulting in more of a rain-snow mix.

Rawlins says 1-2 feet of snow will likely fall in the mountains, resulting in major travel trouble for those driving into the higher terrain.

The current forecast calls for 5-12" of snow to fall at lower elevations, beginning on Wednesday.

Initially, warmer temperatures will result in some rain on Wednesday. But, as colder air moves in, the rain will change over to all snow by Wednesday night.

The snow forecast is dependent on when the rain-snow changeover occurs and whether or not warmer air returns again, changing some of the snow back to rain.
